Python Pygame过渡/按钮未创建持久更改

我正在尝试创建一个游戏，在你点击正确答案后，会出现一个动画，并出现“恭喜”或“再试一次”字样。但是，动画不起作用，文字只在我按下按钮时出现。我怎样才能解决这个问题

我试着将所有代码放在一个while循环中，但这导致游戏窗口根本没有响应

根据变量

woah

绘制结束符号。您可以在游戏的每次迭代中设置

woah=10

if game2 == 0:
    win.blit(divQ1, (200, 200))
    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    woah = 10  # Here!

---

因此，当您不按下按钮时，

woah

将重置，因此不会绘制结束符号。您必须在游戏开始之前设置

woah

，而不是在循环中。

要完成@Rockybilly的答案，当然变量

woah

必须在主循环之前初始化。使用访问函数

mathGame2

中的变量

但同样重要的是，在将文本绘制到显示器上后，执行

pygame.display.update（）

def mathGame2（）：
全球woah

如果game2==0：

#非常感谢！这彻底解决了我的问题。
